In a sauce pot, heat 1 1/2 cups of the stock and 1 tablespoon of the vegetable oil. Bring to a boil and stir in the rice. Lower the heat and bring to a bubble, cover, and simmer until the rice is tender, about 18 minutes. Fluff with a fork and add the scallions.
Meanwhile, thinly slice the chicken or pork.
Trim the broccolini or broccoli and cut into 2-inch pieces or florets. Bring 2 inches of water to a boil in a shallow pot or deep skillet over medium heat. Salt the water and cook the broccolini or florets until tender-crisp, about 3 to 4 minutes. Drain.
Heat a large skillet over high heat while the broccolini cooks. Add 1/2 tablespoon of the oil and when it begins to smoke or ripple, add the chicken and brown it for 5 to 6 minutes, turning once, then transfer it to a plate. Add the remaining 1/2 tablespoon of oil to the pan, stir in the ginger and garlic and cook for 1 minute. Add the tamari, the marmalade, and the remaining 1/2 cup of chicken stock. Slide the chicken, broccolini, and cashews into the pan and stir to combine with the sauce. Simmer for another 1 to 2 minutes.
Scoop the chicken mixture into serving dishes, top with a scoop of rice, and serve.
